1000X
What type of lens in the 100X objective?
Oil immersion lens
Rheostat
Controls the light source in the base of the microscope
Coaxial Drive
Moves the slides of the microscope stage
Which has higher magnification power - Dissecting Microscope/Light Microscope?
Light Microscope
What type of light does a Dissecting Microscope use?
Reflected light (best for viewing large,opaque objects)
Protists
All eukaryotic organisms that are not classified as plants,animals or fungi
Pseudopodia
cytoplasmic extensions that form false feet
What types of protists use pseudopodia?
Amoeba
What is the role of pseudopodia?
Used by amoeba for locomotion and feeding.
What are the 4 defining traits of amoeba’s?
Large nucleus, food vacuoles, outer ectoplasm and inner endoplasm
Contractile Vacuole
Clear, round body that rapidly forms and disappears in Amoeba and other freshwater protists. They pump out excess water gained by osmosis to maintain homeostasis.
Foraminiferans
Amoeba with calcareous tests perforated with tiny pores. Marine organism that makes up sea bed
Radiolarians
Silica tests of many different species - marine organism -make up sea bed
Flagellate Group
Use flagella for locomotion, photosynthetic
Euglena
Part of Flagellate Group - red eyespot, chloroplasts and flagellum
Volvox
colonial organism, large hollow ball of cells each with their own flagella, small daughter colonies inside the volvox colony
